Changing carbs might only make your wallet lighter.
Tell us what it's doing.
And btw your heater hoses are on wrong. Intake to the bottom of the heater core, top of core back to the pump.
The deeper I get in to it the more things I find wrong but I guess I cant complain since the truck was free.

When I got the truck the carb was black inside and it was running rough and it had backfired a couple times. I reset the timing to 9 degrees TDC and adjusted the idle. Now no more backfires.

Now when I put the truck under load after it has been running for a couple mins it wants to stall. I have to really rev it (2,000 rpm) to get it up a hill. It sounds like its sucking a lot of air. I don't have to rev it as much if I let it sit and warm up for awhile. It has a electric choke. I found the Holley manual online and was going to read it tonight.

Thanks for the info on the heater hoses.
